Product Overview
The Konica Minolta Nassenger VII is an advanced textile printing system designed for high-speed, high-quality production. It offers exceptional performance with a maximum printing speed of 210m² per hour and a wide fabric handling capability of up to 1,850mm.
Key specifications highlighted include:
- 512 Nozzles: For detailed and efficient printing.
- 210 m²/h: Maximum printing speed.
- 1,850 mm: Maximum fabric width.
- 900 dpi: High resolution for fine detail.
- 5L Ink Bottles: Large capacity for continuous operation.
The system comprises a scanning print unit and a precision fabric transport unit. For a complete printing solution, a separate un-winder and drier are required.
New Printhead Technology
The Nassenger VII features a newly developed 512-nozzle, high-speed inkjet printhead specifically designed for this system. Utilizing piezo inkjet technology, it prints only when required, ensuring extremely efficient ink usage and making the system economical. The shared mode design requires low drive voltages, contributing to a long service life and making the printheads environmentally friendly compared to other piezo systems.
Productivity and Speed
Print Speed
| Resolution [dpi] |
Speed (m²/h) |
| 540 x 360 | 210 |
| 540 x 540 | 145 |
| 540 x 720 | 115 |
| 720 x 720 | 85 |
| 720 x 900 | 70 |
| 900 x 900 | 55 |
The Nassenger VII is equipped with 24 inkjet printheads, delivering significantly increased production rates – up to 3.6 times more than the previous Nassenger V model. This makes it ideal for low-volume production requiring very fast delivery times.
Fabric Variety and Width
With a maximum fabric width capability of 1,850mm, the Nassenger VII is perfectly suited for a wide range of interior fabric applications, including curtains and bedding. This versatility allows for diverse fabric printing possibilities.

Reliability and Quality Control
The system features an integral nozzle check function designed to ensure stable ink jets from all nozzles. A new head nozzle-check function has been implemented to achieve major improvements in printing reliability.
Ink Jet Sensor Technology (via temperature feedback):
The jet characteristics of each nozzle are detected by a laser sensor. This information is fed back for nozzle monitoring and to set stable jetting conditions. The diagram illustrates the carriage scanning direction, inkjet head, light source, blow-off mechanism, sensor receptor, and sensing emitter.
Quality and Color Accuracy
The new high-speed printhead boasts multi-drop print functionality, producing richer colors and smoother transitions from light to dark tones. Effects unique to inkjet printing are enhanced through the use of multi-drop technology, ensuring accurate production of subtle tints, tones, and color gradients.
High Capacity Ink System
Equipped with high-capacity 10L ink tanks, the Nassenger VII supports long print runs and improves productivity. Inks are supplied in 5L bottles, and in-line degassing units ensure consistent print quality and optimized printhead reliability.
Ink Supply Unit: A unit designed for replenishing ink, featuring a lid that opens for access.
Ink Bottles: Standard ink containers for the system.
Process Comparison: Inkjet vs. Screen Printing
The digital plateless system of the Nassenger VII significantly streamlines the textile printing process. It reduces the time from planning and design to sample creation, enabling higher productivity through mass production. This contrasts with traditional screen printing methods.
Inkjet Textile Printing Process:
- Design: Preprocessing, Image arrangement, Sample printing, Image arrangement, Product printing.
- Post processing: To sewing processing (1-14 days).
Screen Textile Printing Process:
- Design: Image arrangement, Plate design, Colour tracing, Plate making, Ink mixing for sample, Production hardware maintenance/check.
- Post processing: Sample printing, Plate washing/storage, Treatment of waste ink, Production of ink, Production hardware maintenance/check, Product printing, Plate washing/storage, Treatment of waste ink.
- Post processing: To sewing processing (2-4 weeks).
Green and Environmentally Friendly Printing
The Nassenger VII greatly reduces the environmental load compared to conventional processes. Its plateless, on-demand inkjet inks contribute significantly to energy reduction efforts in manufacturing.
Comparison of Environmental Load: Screen Printing vs. Inkjet Printing
- Reduce power consumption: Inkjet printing reduces by 57% compared to screen printing.
- Reduce adhesive paste consumption: Inkjet printing reduces by 97% compared to screen printing.
- Reduce water consumption: Inkjet printing reduces by 62% compared to screen printing.
- Reduce waste materials: Inkjet printing reduces by 85% compared to screen printing.
- Reduce elimination of carbon dioxide: Inkjet printing reduces by 95% compared to screen printing.
